Mississippi State freshman Wade Hummer hammers what will be the flooring system of a house in Diamondhead. Hummer and other members of MSU's Phi Delta Theta fraternity volunteered to work during the winter holidays for the Bay-Waveland chapter of Habitat for Humanity. This marked the fraternity's fourth annual trip to the area affected by Hurricane Katrina, with 35 members providing more than 500 work-hours for low-income families in need of housing.
